Just got the RV back on friday, left saturday for a short trip, 200 mi. Everything seemed ok so far. All I was told about the "check engine light" was that another sensor was replaced. Water heater burner was adjusted, leak around dinette window was fixed. Still have the water leak around the coach door, but Trail-lite has to be contacted to see if the door should be replaced or adjusted. I can't see how an adjustment will work, but have to wait on that. Also received the $200 for the radio replacement, so that's next. The dealer also replaced two plastic roof vents that were cracked by hail while at their lot.
This is the first unit I've driven, but I can say it corners great, I've been through heavy,in town traffic with no problems. Down the road I'd be interested in trying a few others out and compare. We did have a chance to try out the air this weekend, and both the dash and rooftop work great, so far. We're also still on our first tank of propane, used it for the furnace a few times, water heater and the stove burners a few times. We cool the fridge before we leave, shut it off until we hook up at the campsite. Seems to work pretty well that way.
Should know more about the coach door leak in about a week.
